MTL - The Man from Hell - ~ It ’s even more testimonial!

In the magical Yarran World, a group of extraordinary professionals ventured into dangerous places for knowledge, wealth, thrill, and honor, exploring secrets hidden in the depths of time. Coexisting with dangers, they were given a fitting name—adventurers.With so many adventurers around, there would be a few oddballs, of course. Take for instance, the swordsman who used to be a thirsty hedonist and now spent his days looking for ways to put his life in danger; the knight who saw gold coins as his ultimate pursuit; the schizophrenic and overly curious priest, and the genius mage who was prone to zoning out and could not care of himself. What kind of strange stories would these kooky individuals create when they came together?Alright, all the above are just nonsense. In truth, this is a casual story of an abnormal, unscrupulous middle-aged man and a few problematic girls undergoing self-therapy- I mean, seeking redemption.You have been solemnly warned that this story is purely fictional. If there is any glaring similarity, you probably need self-therapy too.

I transmigrated into a novel and became the villainess, Serina who comes from the noble Ducal Melford family.

As a well-to-do character, I tried to mind my own business, but the story had other ideas. A self-proclaimed mother brought back a boy – the duke’s heir and a genius wizard – intent on brainwashing and blackening him.

The contents of brainwashing are two things:

1. Obey our family.

2. And fall in love with Serina.

Thanks to that, the brainwashed twisted yandere is obsessed with me…

I can’t do this. I have to undo the twisted character’s brainwashing!

By the way, what’s this situation?

“Now that the brainwashing is gone, I’ll do as I please. So Serina, please, let’s do our best.”

I’ve solved his brainwashing… but why does he seem even crazier than before—

Did I make a mistake?

Perhaps it is the choice of fate. As a senior otaku, Qian Lingfeng got the “steel shell system”. However, when he swept the world with the system, became a local rich man, made all kinds of beautiful women, opened a harem, and realized the ultimate fantasy of thousands of otaku, he found that things seemed far from simple!
When the end comes, biochemical zombies suddenly come down, fierce beasts are in power, bloodthirsty zerg roam to kill the world, and human lives are comparable to dirt. Where will weak human beings go in this world? Is humanity going to be extinct? Or … can an otaku save the fate of the human race?
